How to resolve?

caumons commented 12 years ago

I have just done a commit which includes new functionality. I also have had a look at the issue you describe and included the fix in the commit. In search() method I was using boolean count instead of Boolean count; where Boolean is seralizable and boolean is not. Notice that all parameters that I am sending to OpenERP are serialized except this, so I think this should solve the problem. Please tell me if this works. Cheers!

It willl error when parameter is NULL .I saw null parameter in openerpconnect.java On Mar 1, 2012 6:30 PM, "Enric Caumons" < reply@reply.github.com> wrote:

I do not understand you. What do dou mean with "I saw null parameter in OpenErpConnect.java"? Where? Have you done a pull and tried the new version? You should call the method with true or false values for count, not null.

If you are referring to line 169, this is the context and I am passing null as we are not actually using it.

If you are still getting errors, please provide more info, stacktrace... in order to find a fix. Else, tellme and I will close this issue.

Go to the file XMLRPCClient.java and put a breakpoint: String faultString = (String) map.get(Tag.FAULT_STRING); int faultCode = (Integer) map.get(Tag.FAULT_CODE); // <== BreakPoint at this line (350)

Now execute the code again with the debugger and copy / paste the value of faultString. With this we will see if the problem comes from the OpenERP response.

Thanks.

Thanks.

Your problem is curious. I am using the connector in an Android app and I am not experiencing this issue...

Have you created the OpenErpConnect instance through the static connect() method with the right connection data?

Before reporting this issue, have you used the debuger to see exactly which parameter is null and is causing the failure? Without this information I can not help you, as I only see the stacktrace of a null serialization failure...

In your code I see that you are using CM_ANDROID. What is this? Is it a string? If you are using connect() to create the instance this value should be a string literal here.

I also see that you are using 1 value for your user id and pass, I guess these values are correct for you.

Also be sure "task.detail.img" is actually a table in OpenERP to which you can access from Web Services.

And finally, test it with other tables, e.g. res.partner.contact and try to use other search conditions.

Cheers.

I have just closed the issue and set it to declined as no more feedback has been provided and I have not been able to reproduce it. This connector is used to synchronize over 125.000 records from an OpenERP server without problems... So I guess your problem is a misuse. Cheers!

Yep I 'll test it. Thank you. On 4/4/2012 6:07 PM, Enric Caumons wrote:

Hi! Pull the latest commit and read the updated doc, I think your issue is because you are trying to connect to "localhost" instead the real IP in which your OpenERP is running. (Read issue #2 for more info).
